following is a specification.

' Britain, residing at Canora,

Be it known that I, Nronoms P. Lnw- 01min, 3, subject of the King of Great in the Province of Saskatchewan and Dominion of Canada, have invented certain new and useful Improvements in Alarm Devices, of. which the This invention relates to signaling means, and more particularly to an alarm for awakening a person at a pre-determined time.

One of the main bjects of the invention is to provide a device whereby the sleeper may be awakened without the necessity of.

disturbing other persons in the same or adjoining rooms.* A still furtherobject is to provide a device of simple tonstruction whereby the signaling or alarm means may be quickly and easily set'for operation at any time desired. 'Another object is to provide a watch in combination with a ring mounted for rotation about the same, this ringcarrying circuit closing means operable by the hour hand of the watch for operating the signalin element, means being pro-.7 V

vided for adjusting the ring about the watch for, the urpose ofsetting the signal. Fur- I ther, ob]ects will appear from the detailed description.

In the drawings V Figurel is a frontview of a signaling device constructed in accordance with my invention,

Fig. 2 is a fragmentary detail view of the circuit closing means, 7 Fig. 3 is a back view with the casing the watch for awa,

Fig. 6 1s a central sectional view through the watch casing, and

v holding frame 1 is pro vided at each end with a slot which receives the end portion of a securing strap 2, these straps cooperating to secure frame 1 on a persons wrist in the well known manner.

This frame is rovided, at each side, with the-'arcuate resi ient arms 3, these arms having the suitably spaced arcuate clips 4 which fit about the edge portion f a casing 5 which contains the watch 6,

This casing,-as v!l l as frame 1 is electrical insulating material. ""The atch casing proper, c. 6., the casing that actually contamsfthe works may also be made of electrical insulating material, though this is not essential under ordinary conditions.

A gear ring 7 of electrical insulating material is mounted about the watch 6 so as to be rotatable thereon, this gear ring being positioned in back of the stem 8. A small pinion 9 'isrotatably mounted in casing 5 and meshes with the gear ring. This pinion serves to move the ring in either direction about the watch, this ring fitting. snuglyon the outer peripheral portion of the watch so as to be frlctionally secured in adjust ment. By this means, ring 7 may be easily adjusted in either directionabout the Watch so as to set the circuit closing means carried thereby in any desired position relative e of' to the hour hand "of the watch so as to cause predetermined time.

- The ring 7 is provided with auintegrfl p d y xtending lugor boss 10', the i1p erfaee'oi this boss being flush with the upper face of the dial of the watch. A movtion or finger 14. A setting lever 15 is pivotally secured intermediate its ends on the boss 10, this lever being bent downward at a right angle and then outward to provide a rectangular or outer end of this lever is curved to provide a resilientlocking head 17 this head being L-shaped portion .16. The

' operation of the alarm device at-any adapted to fit snugly into a cutout or recem I 18 formed in the tooth 19 of gear ring? so as to be frictionally gripped thereby thus releasably securing the lever in operative position. As will be noted more clearly from the; drawings, the inner arm of lever 15 extends beyond the pin- 13 of contact arm 11 thus acting to hold this member in set position extending inwardly above the dial of the watch. A. small wire spring 20 is secured on the boss 10 and presses against the inner arm of setting lever 15 inside of, the pivotal axis thereof. -This spring serves} to counteract to a great extent the frictional binding of head 17 in the recess 18, thus gw as to complete the circuit of ing a very delicate sothat the hour hand 12 can easily move the contact arm 11 when it the same. When the=hour hand engages the member 11, it swings it outward. so as to bring it into ent wlth a contact pin 21 secured 10, thearm being provided with a bent portion 22 which serves as a catch for releasably so curingthearmin entwiththe or pm 21," ,when' moved into out therewith by'hand'12-- By this incans,'the pins 13 and 21'are'electricalg connected so alarnielement. Asthering'lcan q ui and easily about the watch, it be evident thatthe device can be readily set to operate at any pro-determined time.

Also, the teethof the pinion 9 for operat' "ring7serveto'"theroundedhead1 of setting lever 15 so asto move the same into recem 18, thus moving the contact arm 11 into operative positionin the manner reviously escribed. It will'be und of course, that the contact arm 11 projects in- 255 wardly above the dial of the watch beneath 5 23 which is.carried by thecase watch 6 issupported by 'a boss 24 formed integral with, and at the center of a disk-like supporting member 25 mounted in casing 5 and provided with an upwardly directed peripheral flange '26 which is of somewhat greater height than boss 24 and acts' to support the ring 7. By this construction, an annufi neath the watch, this space providing a compartment which receives a cable 27 which is spirally coiled about the boss 24. This-cable'contains the wires28 and 29 which are connected to the pins 13 and 21 respectively, at one end. The other ends oi these wires are connected to the opposite poles of an elett'ic cell or battery 30 which is secured to 1. An alarm element 31 is mounted on e back of the casing o32containingthecellandisinterposedin the wire 29. This element may be made of.

switch may be moved into engagement with thecontact34so asto permit ecircuit of the alarm device or element 31 to be completed when the arm 11 is moved into ent with. in 21. This control switch maybemoun onthebatteryfiOandmag be of serving also space isformedbed. A control close the circuit for operating the light 35.

which is connected to theoles of the batto bring contact arm 11 into position above the time on the dial of the watch to which 'it is desired to operate the alarm, and then moving the switch 33 into position to close the alarmcircuit (indicated by A), the

alarm will be operated at the desired time so as to heat the member 31 and thus awaken the wearer. In addition, the light 35 may be utilized by moving the switch 33 into the position'indicated by L so as to complete the light circuit. This li ht is of usual c0nstruction, and is prote by a hinged cover 40 when not being used.

In the form shown in Fi 5, the casing 5 provided, at opposite si' es thereof, with 5 which are adapted to receive spring-pressed securingpins 41 which are carried by the arms 42 of the holding frame 1. In this case, the wires 28 and 29 are connected to sockets 43 and 44, respectively, secured in the casing 5. These sockets are adapted to receive the studs 45 and 46, respectively', to which are connected the wires 47 and 48 of the cable 49, the other ends of these wires being connected to the poles of the battery or cell carried by casing 32. This constructiompermits'the watch to be readily removed from the holding frame so as to be carried in a pocket in the usual manner, the cell 32 and holding frame, being also carried in the pocket if desired. When the watch is inserted into the holding frame so as to bring the pins 41 into engagement with the recesses 5, the studs 45 and 46 will engage into the sockets 43 and 44, respectively, so as to electrically connect the pins 13 and 21 to the poles of the battery 30 after which-the device willoperate in the manner above outlined.

It will be evident that there may be slight changes made in the construction and arrangement of the different parts of my invention without departing from the field and scope of the same, and I intend to include all such variations, as fall within the appended claims, in this application in which a preferred form only of my invention is disclosed.
